In summary, Plundervolt exploits Intel Software Guard Extensions (SGX), which is a set of instruction codes that undervolting programs like Throttlestop and XTU use to manipulate CPU voltages. You can read the research team's findings in its research paper, which can be found here. There is no one catch-all here, but the reasoning behind disabling undervolting is Plundervolt, an exploit discovered by the University of Birmingham.


While Dell has warned that undervolting can void warranties, Intel and some OEMs have gone a step further and have disabled undervolting altogether.

Two of the most popular undervolting programs are Intel Extreme Tuning Utility (XTU) and Throttlestop, the differences between which you can read in our guides to using the programs. It has been a few years since we published guides on undervolting, the act of restricting CPU voltages to reduce temperatures and improve battery life.
